Into which subcategories can reinforcement learning be divided?
Your two suggestions are not mutually exclusive. If you go by this process, you'll have to do a &quot;Cartesian product&quot; of a bunch of different RL categorizations which would get out of hand. I recommend, if you can, to describe some sort of &quot;RL taxonomy&quot; instead. By this I mean describing different RL characterizations without assuming they're mutually exclusive.
To add to your list :

On-policy or off-policy
Value based or policy gradient
